I've seen Slash's Snakepit three or four times over the years opening for Aerosmith and AC/DC, and obviously I have seen Slash with VR a few times. Check.
I have seen the GNR incarnation that included Buckethead in 2002. Got my fix in of the GNR tunes I wanted to hear. Check.
Like someone mention, I am not going to burn $100 to see 3 of the original 5 members. I would MAYBE consider getting the cheapest seats possible and tailgate with friends. But $250 for GA? I'll pass.
